/**
 * << README >>
 * Github Issue: https://github.com/sachinraja/trpc-playground/issues/55
 *
 * This file is a workaround for fixing issues with the schema generation for the trpc-playground package
 * with the V11 tRPC release. This file fixes an issue where the typescript types for the router are not resolved correctly
 *
 * This is due to the fact that the trpc package made some breaking changes to the router type
 * Issues this file fixes:
 *  - _def.query and _def.mutation are now replaced by a _def.type field which can be 'query' | 'mutation' | 'subscription'
